Book Pink Bollworm Management in Cotton in the Southwestern United States Classic Reprint

Download or read book Pink Bollworm Management in Cotton in the Southwestern United States Classic Reprint written by T. J. Henneberry and published by Forgotten Books. This book was released on 2018-05-14 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Pink Bollworm Management in Cotton in the Southwestern United States The first pink bollworm infestations in eastern Arizona were reported in 1926. At intervals thereafter, they occurred in other parts of the State and were suppressed through cooperative Federal, State, and industry programs, but infestations spread rapidly after termination of the cooperative efforts in 1963 and were found in the Imperial Valley of California in 1965. Spread was rapid throughout southern California and severe losses occurred by 1967. Infestations were detected in the high desert areas of Los Angeles and San Bernadino Counties in that year, and four moths and six larvae were found in the San Joaquin Valley near Bakersfield. Varying numbers of native moths have been trapped each year except for 1968, and a few larvae were found in the San Joaquin Valley in 1970, 1977, 1980, and 1983. However, by 1985, the San Joaquin Valley remains the only cotton growing area in the Western United States without a firmly established pink bollworm population.

Book Pink Bollworm Control in the Western United States Classic Reprint

Download or read book Pink Bollworm Control in the Western United States Classic Reprint written by Harry Morgan Graham and published by Forgotten Books. This book was released on 2018-01-12 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Pink Bollworm Control in the Western United States Avoidance of early planting can reduce the numbers of moths that survive to infest cotton in the spring. If planting is too late, however, it can result in yield losses, increased damage by late season infestations of insects such as the tobacco budworm, and increased proportions of the pink bollworm and other pests entering the overwintering stage. The most practical approach to reducing pink bollworm populations is to plant when optimal conditions for seed germination occur, produce a heavy boll set before the extreme summer heat reduces fruiting, and terminate fruiting earlier than it is now normally accomplished. At present, early termination of fruiting is limited to cessation of irrigation and to early maturing varieties. An irrigation termination of August 1 at Yuma, Ariz., reduced overwintering pink bollworm populations with no reduction in yield compared with later irrigation termination dates. This date would have to be altered for other locations, depending on soil type and other factors. Not only does the production of an early cotton crop decrease overwintering pink bollworm populations, it also may result in increased quality of the cotton by avoiding insect damage, boll rot, and storm damage that can occur in later cotton. Plant growth regulators have been used effectively to terminate cotton fruiting. These may have some advantages over irrigation termination, but none is registered for this use on cotton as yet.

This book was released on 2017-10-13 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Report on Investigations of the Pink, Bollworm of Cotton in Mexico Bolls and squares were used, but the squares were found more satisfactory. The food with the young larvae was placed in vials plugged with cotton. The pieces of bolls would become discolored, decomposed, and unsuitable for food in one or two days, while a square would remain in good condition several days and the larva could be examined daily with less disturbance. Wire cages were also used over small potted plants and cotton plants in the experimental plat to check the laboratory results. The pupae were removed to glass vials with a piece of damp cotton in the bottom to provide the necessary humidity.

This book was released on 2018-09-19 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Kill of Pink Bollworms in the Cotton Gin and the Oil Mill Most of the larvae of late-season generations of the pink bollworm remain in bolls and there enter the diapause, or resting stage, in which, under natural conditions, they live through the winter. Lar vae that survive the winter in the field do so mostly in waste cotton remaining after harvest. It has long been recognized that cotton infested with the pink bollworm should be harvested thoroughly and transported in a way that avoids deposition of waste along road sides, in order that as many as possible of the worms may be carried to the gin rather than left to infest the next year's crop.
